A square is an example of a quadrilateral that is both a regular concave polygon and a regular convex polygon?
No. There can be no regular concave polygon.
Is a concave polygon a regular polygon?
No, a concave polygon cannot be a regular polygon.
Can a regular polygon be concave or convex?
no it cannot , because a regular polygon is a shape with equal sides, and for it to be concave or convex some sides have to jut out or in See related link below for more information
What are the similarities between regular polygon and a concave polygon?
A regular polygon is a special kind of convex polygon - one in which all the sides are of the same length and all the angles are equal. Convex and concave polygons form disjoint sets: so no concave polygon can be regular.
Can a concave figure be a regular polygon?
No.

Is a star shape an irregular polygon?
Not all are. Not only is it a concave shape, but the interior angles can vary. For a polygon to be regular, it must be equilateral and equiangular.

A pool is in the shape of a polygon. The segments and vertices of the polygon are shown. Is this polygon convex or concave?
concave

Can a concave qudrilateral be a regular polygon?
no
What is the difference between a concave polygon and a convex polygon?
Any polygon that has an angle that is > 180º is a concave polygon. A convex polygon does not. e.g. All regular polygons are convex.
How do you draw a regular concave polygon?
it is impossible
Why can't a concave quadrilateral be regular?
By definition, a regular polygon has all interior angles the same, but a concave polygon has some interior angles that are not identical. Also, it violates the axiom that all vertices lie on a circle.While it is possible to construct a polygon with equilateral sides, to be concave would require a form that is equally convex and laterally opposite. (An example is a 'solid arrow shape.')
